An object model for natural language document

Abstract

An object model of a text is defined, and structural and manipulative aspects of the model are presented. The model proposed supports text in its general sence (as a natural language document), which comprises structural, syntactic, semantic, orthographic, stylistic properties of both the underlying natural language and the text itself. Extended class algebra is defined as a basis for manipulative part of the model. Set of classes is then proved to be closed under the operations of the extended class algebra.
